Try to solve error about create-react-app - reactjs

Every time I try to run npx create-react-app my-app, the same error will show:
A template was not provided. This is likely because you're using an outdated version of create-react-app. Please note that global installs of create-react-app are no longer supported. You can fix this by running npm uninstall -g create-react-app or yarn global remove create-react-app before using create-react-app again.
I did whatever this error said. Try using another text editor rather than VSCode and try all of the ways that people suggested in related topics, but nothing works.


check whether create-react-app has been uninstalled by typing which create-react-app, if it is not uninstalled it will exit the create-react-app folder located ex : /usr/bin/create-react-app. then delete with rm /usr/bin/create-react-app


It is maybe because you are not using the latest create-react-app version.
If you are using npm 5.1 or earlier, you can't use npx. Instead, install create-react-app globally:
npm install -g create-react-app
then run:
npx create-react-app my-app
See all information here.
Hope this answers helps you.

Error while creating new react app (You are running `create-react-app` 5.0.0, which is behind the latest release (5.0.1).)

(I am using ubuntu.)
the message i am getting:
You are running create-react-app 5.0.0, which is behind the latest release (5.0.1).
We no longer support global installation of Create React App.
Please remove any global installs with one of the following commands:
npm uninstall -g create-react-app
yarn global remove create-react-app
The latest instructions for creating a new app can be found here:
https://create-react-app.dev/docs/getting-started/
I have already tried:
npm uninstall -g create-react-app
npx clean-npx-cache
npx create-react-app#latest project-name
Nothing works
what should i do now?

I know it is late but...
I also had the same problem and every solution I found didn't seem to work. In the end I found it out.
I have both yarn and npm installed
create-react-app was installed in both and they were referencing each other
You need to perform both if you have both yarn and npm
npm uninstall -g create-react-app
yarn global remove create-react-app
Then clear cache using one (or both)
npx clear-npx-cache
npm cache clean -f
Then run to install and create the app
npx create-react-app#latest your-app-name
Hope it helps someone :)

npx create-react-app gives error need to install the following packages: create-react-app

I'm trying to install react to create a project in vs code. When I try doing this using npx create-react-app frontend I get:
Need to install the following packages:
create-react-app
Ok to proceed? (y)
Which then gives me an error saying that:
You are running `create-react-app` 4.0.3, which is behind the latest release (5.0.1).
We no longer support global installation of Create React App.
Please remove any global installs with one of the following commands:
- npm uninstall -g create-react-app
- yarn global remove create-react-app
The latest instructions for creating a new app can be found here:
https://create-react-app.dev/docs/getting-started/
I entered npm uninstall -g create-react-app and followed the latest instructions , but the the latest instructions say to use npx create-react-app, and when I try it again I keep getting the exact same issue. Does anyone know why this is happening or how to fix this?

You need to uninstall the global installation first which you did but in my case I had to clear the cache too.
try this:
npx clear-npx-cache

A template was not provided. This is likely because you're using an outdated version of create-react-app

I am trying to use create-react-app to generate a new React app.
I run
npx create-react-app my-app
But I am getting this error:
A template was not provided. This is likely because you're using an
outdated version of create-react-app. Please note that global installs
of create-react-app are no longer supported. You can fix this by
running npm uninstall -g create-react-app or yarn global remove
create-react-app before using create-react-app again.
I tried running
npm uninstall -g create-react-app
and I verified that it does not exist globally, but still getting this error.
How do I fix this?

OK. I found a real simple fix for this.
which create-react-app | xargs rm
I guess there is some artifact from an old install that doesn't show in the npm global list that is causing the problem.
Once it is removed there is no need to install anything. Just run:
npx create-react-app my-app
And it will work now.

create-react-app doesn't generate public and src folders thus cannot get started

i have installed CRA for over a month and have been working with it without having any problems, however today i created a new react app and it builds the folders and directories except it doesn't generate src and public folder(it just generated node-modules folder) thus when i run npm start it gives me an error saying:
npm ERR! missing script: start

Initially you might have installed create-react-app globally.Try to remove using npm uninstall -g create-react-app command and then try npx create-react-app <your-app-name>.
The reason is, npx should use it's latest version to work. Hope your doubt is now cleared

I still have no idea what was the reason but I got it working doing these:
-uninstalled create-react-appusing npm uninstall -g create-react-app.
-using npx create-react-app app-name I created a new app and now it's working as expected.

I have tried installing in different computers and for most cases the above codes helped to fix the issue. But in a rare case I had to use another code and it worked perfectly. Try running the below code
npx --ignore-existing create-react-app Your-AppName

I tried all the suggestions stated above but none works for me.I just run these commands and create a new project.
npm rm -g create-react-app
npm install -g create-react-app
npx create-react-app#latest my-app
This work for me.

You can create project with yarn:
yarn create-react-app my-app

Create React App not working

Help! I have no idea what is going on here, create react app is not working I have also tried reinstalling and yet to no avail, please help!
Npm version: 5.4.2
Node version: 8.70
Tried the npm install --save --save-exact --loglevel error react react-dom react-scripts

In my case, "create-react-app" was not installed. to install run this command
npm install -g create-react-app
Once installation successful, try running
npx create-react-app hello-world
If this works for you. Great else comment what worked for you,

Please try this:
npm cache clean --force

I also got the same issue and tried to resolve for a long and finally resolved using this command,
npx create-react-app#latest my-app --use-npm

I had the same problem and had to do the following:
npm uninstall -g create-react-app
npm uninstall create-react-app
After this I was able to create the app with:
npx create-react-app project-app

I had the same problem, and I solved it by:
1. update the npm version (npm install npm#latest -g)
2. clear the cache (npm cache clean --force)
3. create the react project (npx create-react-app todo)
(create-react-app was already installed)

I had similar issue while tried creating new react app with create-react-app, but related to some random JSON reading issues while installations like.. >= 5.0 || 4.0 ..
But the fix below solves multiple and similar issues.
First of all, make sure you have required or latest version of node installed.
npm install npm#latest -g
Before using create-react-app make sure you clean npm cache using npm cache clean --force
Now, is should be fine to create new react app with npx create-react-app tl-app or npx create-react-app . if you want to create current directory as project root.

Make sure you are not running any antivirus, stop/pause all antivirus or protection software.
You can also try
use create-react-app projectname --save
or create-react-app projectname --save-exact and start again
OR
as the error suggests, you should use a newer version of node. You are using 8.9.4, you should probably use 8.12.0 LTS.

It sets up your development environment so that you can use the latest JavaScript features, provides a nice developer experience, and optimizes your app for production.
You’ll need to have Node >= 8.10 and npm >= 5.6 on your machine. To create a project, run:
npx create-react-app my-app
cd my-app
npm start
Note:
npx on the first line is not a typo — it’s a package runner tool that comes with npm 5.2+.
Create react app provides more information regarding this.
It may be the problem of cache also, so can also try:
npm cache clean --force
Edit 1: This may be due to slow internet speed, Please check the
internet and try again.

npx create-react-app .
( the .) means create project on this folder so you should manually create if you do that

For the windows machine following command worked for me
yarn create react-app my-app
cd my-app
yarn set version berry
yarn
yarn start

The problem on my machine was caused by yarn. I am windows 10 and after uninstalling yarn using npm uninstall -g yarn, my script run correctly. So
Open terminal and type: npm uninstall -g yarn
Once done, close terminal and open new one
type create-react-app (app name) and this should create your app :)
Please note that the above steps assume that you already have node and react-cli installed on your machine.

on Ubuntu 18.04
sudo npm cache clean -f
sudo npm install -g n
sudo n stable

What I did, is going to
C:\Users\mycomputerName\AppData\Roaming\npm\
I changed the name of this file
create-react-app.ps1
to
create-react-appOld.ps1
or you can delete it, then it worked fine

Tried all the above methods but no luck:(
Step1 : Reinstalled Node js
Step2 : Check whether environment variables has been created. if not create one for nodejs,npm and composer
Step3: Also add "C:\Windows\System32" to the global PATH environment variable.
Step4: Then use "npx create-react-app my-app" to create react project
Step5: Run the commmand : cd my-app and npm start
Step6: It will work

I finally got it to work. An anti-virus in my system was causing it not to work property. I unistalled it and it's working as expected.

After no luck with updating my npm version and doing npm cache clean --force I ended up just doing a fresh install of node which fixed the issue for me.

HAD the same problem. Running Node with cra. installed cra -g for starters.
npm install -g create-react-app
then downgraded react-scripts to version 2.1.8
npm install react-scripts#2.1.8
created a .env file in root directory and added this to it.
DB_HOST=localhost
DB_USER=root
DB_PASS=s1mpl3
SKIP_PREFLIGHT_CHECK=true
Then you do the typical delete node_modules folder and the package-lock.json file.(NOT PACKAGE.JSON!!!)
then:
npm install
npm start
This worked for me. Sorry I'm not more informative on why this worked for me. I'm still trying to understand why it didn't work in the first place.

I just did it now after messing around with it all yesterday.
Installed react globally like people have said.
then I used 'git bash here' to open terminal in the directory i want
oddly, it worked when I removed npm. I know it's weird, I've never had to do that and it makes no sense but its working so:
create-react-app my-app-name
I'm on windows 10 by the way.

If there is anyone having this issue that you can not find your project when you
yarn create-react-app (name of project)
npx create-react-app (name of project)
then just be sure that you are in the right directory.
use this command in your terminal
cd ..
now search the project name by
cd (project name)
you should find your directory here.

Please do this, I hope it will fix all of your problems
1- npm i -g create-react-app
2- create-react-app my-app

Find the folder and where a folder named npm is present and add it into environment variables (path)

I also experienced the same problem and SOLVED IT.
This is what I did.
Restart your machine(computer)
Deactivate your anti-virus. I chose the "permanently" option
Open the terminal and run the "create-react-app" command again, It will definitely do the trick.
Activate your anti-virus
And get working :-)
